Weyl, Identity, Indiscernibility

In his interpretation of the foundations of non-relativist quantum mechanics, Hermann Weyl developed a technique to accommodate aggregates of quantum particles while taking into account these particles’ apparent lack of identity. The technique makes sense of putative restrictions on the applicability of identity in QM without changing either the underlying logic or the relevant set theory. I reconstruct this technique and assess its feasibility, contrasting it with attempts to make sense of the foundations of QM by jettisoning identity entirely and revising the underlying logic and set theory (French and Krause [2006]). I argue that Weyl’s approach has significant benefits.
